HEAD-GATE.

To all whom it may concern:

Be it known that We, JOHN Z. HANSON and WVILLIAM D. THOMAS, citizens ofthe United States, and residents of Aberdeen, in the county of Binghamand State of Idaho, have invented a new and Improved Head-Grate, ofwhich the following is a full, clear, and exact description.

Our invention is capable of embodiment either in a permanent head gate,or in a portable head gate adapted to be located at any point in aditch,to raise water therein where desired.

It is an object of the invention to provide an improved valve means forcommanding the opening in the gate, and a novel arrangement ofmanually-controlled operating rod and guide therefor.

The invention will be particularly explained in the specific descriptionhereinafter to be given.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a front elevation of a head gate embodying our invention,showing the same in position for use; Fig. 2 is a sectional plan view;and Fig. 8 is a side elevation with parts broken away.

In forming a head gate in accordance with our invention, the body 10 ofthe gate is preferably formed of a plate and is of a size to rangeacross a ditch, as indicated by the letter A, to regulate the height ofthe water B at the front of the gate. Said gate is provided with asuitable opening for the water, and surrounding said opening is anannular flange 11, that extends forwardly. If the gate is employed inthe head ditch in a permanent position, it may have a rear flange 11 toreceive any suitable lateral pipe (not shown) to extend through the bankof the ditch.

The opening through the gate is commanded by a valve disk 12, having aperipheral ear 12 which is pivoted on a post 13 that extends forwardlyfrom the gate 10 parallel with the flange 11 and outwardly beyond thelatter. The valve can be swung on" its pivot by means of amanually-controlled operating rod 14, which is pivoted at Specificationof Letters Patent.

Application filed March 12, 1913.

Patented Dec. 30, 1913. Serial No. 753,730.

14, to a peripheral ear 12 on the valve disk, said rod extendingupwardly in front of the gate, above the top thereof, and having guidedmovement in a horizontal keeper bar 15 which is connected-by the legs 15with the gate 10. The operating rod 14 is provided with a suitablehandle, preferably by forming a rearwardly extending arm 14 thereon atthe outer end, which is disposed above a horizontal, forwardly extendingflange 1O on the top of the gate. The flange 10 constitutes a handle orgripping member to be utilized in placing and removing the gate.

The valve disk 12 is pivoted to the rod 14 in a position to bear againstthe outer edge of the forwardly extending flange 11, the pivot ear 12 ofthe valve being disposed at the inner side of a fixed member 16preferably in the form of a disk or collar on the post 13, to bearagainst the said inner side of the member 16. A retractile, helicalspring 17 is secured at one end to the valve disk 12 adjacent to thecollar 16, and the opposite end of the spring is secured to a presserbar 18 pivotally mounted 011 the post 13, at the outer end of thelatter, said presser bar extending in the direction of the valve diskand terminating in a foot 18 which is parallel with and has a bearing onthe outer face of the valve disk. The foot 18 is free to sliderelatively to the valve disk 12 within a keeper 19 on said disk.

It will be observed that the spring is connected with the presser bar 18at a point farther from the pivot post 18 than the connection of thespring with the valve disk, so that the force of the spring will act onthe presser bar through a longer lever arm than in its action on thevalve disk, so that the increased leverage causes the force of thespring to be greater on the presser bar than on the disk, the result ofwhich is that the spring acting through the presser bar will tend tohold the valve tightly against its seat on the flange 11 in any positionto which the valve has been moved by the operating rod 14.

To facilitate the placing of the gate in position, its bottom edge isconvexed and formed with teeth 20, giving the said bottom edge the formof a saw. By means of the bottom 'saw edge and the handle portion 10,the gate may be caused to readily cut its way into the ground whenplacing the gate in position.

Having thus described our invention, We claim as new, and desire tosecure by Letters Patent:

1. A head gate having an opening, an annular flange on the gate at theopening, a pivot post on the gate extending forwardly beyond the flangeand having a fixed bearing member adjacent to the outer end of theflange, a valve disk having a peripheral ear pivoted on the postadjacent to the inner side of the said fixed member, to bear against thelatter, the valve being adapted to be swung across the opening in thegate close to the annular flange, a manually-controlled operating rodpivotally connected with the valve disk and having guided movement onthe gate, a presser bar pivoted on the post at a point outward from thevalve disk and mentioned fixed member, and extending to the said valvedisk, the outer end of the presser bar having a foot parallel with thevalve disk and bearing thereon, a keeper on the valve disk beneath whichthe foot of the presser bar has sliding movement on the valve disk, anda helical retractile vspring secured at its ends to the valve diskandpresser bar respectively, the point of connection between the springand presser bar being farther from the pivot post than the connection ofthe spring with the valve disk.

2. A head gate having an opening, an annular fiange on the gate at theopening, a post on the gate extending forwardly beyond the flange andhaving a fixed bearing member, a valve disk pivoted on the post andlying beneath the inner surface of the fixed member, to bear against thelatter, a presser bar pivoted on the post, and a retractile springconnected at one end with a valve disk and connected at its opposite endwith the presser bar at a pointfarther from the pivot than theconnection of the spring with the valve disk.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing Witnesses.
